Studies on the Activation Energy of Photographic Development

Abstract

The activation energies of image and fog development of a commercial film by two developers with and without the fog restrainers were calculated. The activation energies of image development were smaller than those of fog formation. When the fog restrainers were added, the activation energies increased for both image and fog development and the increase was larger for fog than for image. The difference between image and fog and the effective action of the fog restrainer were discussed from these results.
